资源说明:A shell just for fun
Shelldone is just a shell written in C from scratch so I can play with it. I guess it will never be as complete as zsh/csh/bash/whatever, but actually it is not my goal. I'm just working on it to learn and improve my skills in C programming. Compilation ----------- $ make Execution --------- $ ./shelldone Features -------- - Jobs control (command jobs, fg, bg + SIGTSTP (^Z) ) - Arguments protection: "an example", 'another example' - Multi-line commands (with a final backslash (\) ) - Multiple commands: ls | grep .c && echo OK - Background commands: sleep 120 & - Extensible with modules (see README in plugins directory) Example ------- ziirish@carbon:~/workspace/shelldone/src$ valgrind --leak-check=full --show-reachable=yes ./shelldone ==22418== Memcheck, a memory error detector ==22418== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al. ==22418== Using Valgrind-3.6.0.SVN-Debian and LibVEX; rerun with -h for copyright info ==22418== Command: ./shelldone ==22418== shell> module load ../plugins/parsing/jobs/jo jobs.c jobs.so shell> module load ../plugins/parsing/jobs/jobs.so Module 'jobs' successfuly loaded. shell> ../../test/bl blah blah.c shell> ../../test/blah 1 2 3 ^Z [1] 22421 (../../test/blah) suspended shell> ../../test/blah 1 2 3 ^Z [2] 22422 (../../test/blah) suspended shell> ../../test/blah 1 2 3 ^Z [3] 22423 (../../test/blah) suspended shell> fg %1 [1] - continued 22421 (../../test/blah) 4 5 6 ^Z [1] 22421 (../../test/blah) suspended shell> fg %3 %2 %1 [3] - continued 22423 (../../test/blah) 4 5 6 7 8 9 10 [2] - continued 22422 (../../test/blah) 4 5 6 7 8 9 10 [1] + continued 22421 (../../test/blah) 7 8 9 10 shell> quit ==22418== ==22418== HEAP SUMMARY: ==22418== in use at exit: 0 bytes in 0 blocks ==22418== total heap usage: 6,933 allocs, 6,933 frees, 725,868 bytes allocated ==22418== ==22418== All heap blocks were freed -- no leaks are possible ==22418== ==22418== For counts of detected and suppressed errors, rerun with: -v ==22418== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 4 from 4)
